Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, dial indicator, torque wrench, brake cleaner, and OBD-II scanner.
Safety Warnings: Ensure the vehicle is on a level surface, and wear safety goggles and gloves.

2. Lift the Vehicle

Use the jack to raise the front of the vehicle.
Secure it with jack stands for safety.
Remove the front wheels using the lug wrench.

3. Inspect and Replace Brake Rotors (if warped)

Inspection:
- Use the dial indicator to measure rotor runout. If it exceeds the manufacturer's specifications, the rotor is warped.
Replacement:
- Remove caliper bolts and slide the caliper off the rotor. Support it with a bungee cord to avoid straining the brake line.
- Remove the rotor by unscrewing any retaining screws or removing the caliper bracket if necessary.
- Install the new rotor and secure it in place.
- Reinstall the caliper over the new rotor.

4. Replace Brake Pads (if worn)

Remove the caliper bracket if it was not removed in the previous step.
Take out the old brake pads and inspect them for wear.
Apply brake grease to the backing of the new pads to prevent squeaking and install them.
Reattach the caliper bracket and ensure all bolts are torqued to the manufacturer's specifications.

5. Inspect and Replace Suspension Components (if damaged)

Visually inspect control arms, bushings, and struts for any signs of wear or damage.
Replace any worn components as necessary. This may involve:
- Removing the bolts securing the component, replacing it, and torquing to specification.

6. Reassemble and Test

Reinstall the front wheels and lower the vehicle.
Torque the lug nuts to the manufacturer's specifications.
Test drive the vehicle to verify the shaking issue is resolved.
